Bug#994743: keyboard-configuration should trigger update-initramfs or warn about it

[piorunz <piorunz@gmx.com>]

Package: keyboard-configuration
Version: 1.205
Severity: important
X-Debbugs-Cc: piorunz@gmx.com

Dear Maintainer,


1. Changed my keyboard layout to GB Colemak via "dpkg-reconfigure keyboard-
configuration"
2. Rebooted
3. All changed were ignored to my surprise.

After a lot of digging and discussion in Debian User mail group, I realized
that "pkg-reconfigure keyboard-configuration" did not trigger update-initramfs.
All my changes have been ignored. And it would stay that way, until I install
new Debian kernel or update current one. I had to do "update-initramfs -u -k
all" to have my keyboard layout changed.
This bug renders keyboard-configuration unusable, until user knows magic
command which needs to be done after.

Solution 1:
"dpkg-reconfigure keyboard-configuration" should warn about required update-
initramfs, otherwise changes are not implemented
Solution 2:
"dpkg-reconfigure keyboard-configuration" should update initramfs

I use Debian Stable with KDE, no exotics.
